The answer is 3x-12y because you combine the like terms so 2x+x=3x and -8y-4y=-12y

Answer: 3x -12y

Step-by-step explanation:

Hi, to answer this question we have to add both expressions, the times "from" and "to" school.

Total time spent: time to school + time from school

Mathematically speaking:

  • x − 8y + 2x − 4y

Adding alike terms:

  • x +2x -8y- 4y =
  • 3x -12y

In conclusion, the expression that represents the total time Henry spends commuting to and from school each day is 3x -12y.
